If the motorcycle engine is the "core person" of the "organization" of the motorcycle, then the clutch is the "joint" of the "core person". Similar to the role of the joint in the movement of the human body, the clutch in the operation of the motorcycle is to play a smooth start, transfer power, shift smooth role, so the clutch is a set of motorcycle safety, usability, comfort in one of the key parts. Here is a talk about the clutch in the use of several main failure modes - slipping, abnormal noise, burning.

(1) skidding - the phenomenon of skidding is mainly manifested as: in the motorcycle starting, accelerating, uphill or other situations due to the increase in load when there is weakness, impulse, regression and other phenomena, the main reason can be attributed to the friction of the clutch combination can not meet the normal driving force caused by.

There are more factors causing the skid phenomenon, and the following factors are for your reference:

1, clutch friction plate material difference. Through the domestic different manufacturers of friction pieces and domestic and foreign pieces in the same test conditions to be verified by the experiment, it is proved that under the same conditions, the wear resistance of high-quality pieces (mainly refers to the same load under the use of time) is more than 2 times of ordinary pieces. Of course, the price of high-quality foreign films is also more than twice the price of ordinary films. Users can choose high-quality pieces or ordinary pieces according to their needs.

2, vehicle overload caused by abnormal clutch wear. Many users, especially rural users, often ignore the manufacturers' requirements for the maximum load capacity of motorcycles when using motorcycles. Often the weight requirements in the case of 150Kg overweight to more than 200Kg, so that the clutch wear is aggravated, will soon appear skidding phenomenon, so the user should try not to overload the car to achieve the purpose of protecting the clutch.

3. Improper engine use and maintenance. It is mainly manifested in the following aspects: first, the oil is not replaced for a long time, and the oil with high viscosity and iron filings is the main factor causing the surface wear of the clutch friction plate; The second is that the clutch control mechanism is loose, and the user is not adjusted in time, so the clutch is working in a semi-clutch state for a long time, which is a very dangerous working condition. It is understood that a well-known motorcycle company in China has repeatedly broken the main and auxiliary shafts when shifting due to the automatic clutch control mechanism loosening.

(2) Abnormal sound - the main phenomenon is: abnormal sound is generated at the moment when the load changes or the clutch engages during the driving of the motorcycle. The main factors are as follows:

1, the wear between the friction sheet and the steel sheet is uneven, and the sharp cry is generated at the moment of engagement.

2. The contact surface of the friction plate and the center sleeve and the pressure plate can not penetrate into the contact surface due to the oil viscosity SampleText degree and other reasons, resulting in dry friction and abnormal sound.

3, in the process of use, the loosening of the locking mechanism or the loosening of the adjusting mechanism will cause the clutch dynamic balance imbalance, long-term use, and there will be a large abnormal sound between the matching parts.

The user can adjust the abnormal noise of the clutch caused by the above three factors through daily maintenance and replacement of relevant parts. In addition to the above three, the flatness of the clutch friction plate is excessive, and the thickness of the friction plate is uneven can cause the clutch abnormal sound. This point requires the clutch manufacturer to strictly control its height difference and flatness in accordance with the standard to achieve the purpose of reducing the abnormal noise of the clutch.

(3) Burning sheet - the most intuitive phenomenon of burning sheet is that the friction material and the main body fall off. The main reasons can be divided into the following points:

1, friction material bonding is not strong. The main phenomenon is that some friction materials remain on the main body after burning, and the probability of this situation is very small, because the friction sheet manufacturer will comprehensively test the adhesion of the friction sheet before leaving the factory;

2, the friction sheet can not withstand excessive load caused by the friction sheet ablation. The main performance is that the friction material all falls off, the appearance is charred and has a burnt taste. There are quite a lot of factors caused by this phenomenon, such as overload driving, poor oil quality, poor friction materials and incorrect clutch operation mode (such as semi-clutch climbing, uphill shift blasting oil speed up, etc.) may cause serious erosion of the friction plate.

Burning film has a considerable impact on driving safety, and it will cause a major accident if you are not careful, so please strengthen your own safety awareness, correct use, and reasonable maintenance of your car.
